    An arrangement for supplying powdered material to a spraying device in an installation for thermal spraying comprises at least one powder storage container and an injection device by which the powder is introduced into a stream of carrier gas. A buffer chamber is disposed upstream of the injection device and comprises means for controlling the level of the powder, at least one controllable feeding means being connected, by means of a control device, to the level-controlled buffer chamber. The present arrangement allows to obtain a well-defined rate of flow of powder which is constant and adjustable, from one or more powder storage containers.

    专利说明:

    The invention relates to the pneumatic transport of bulk materials, namely to the distribution device of powder materials for the installation of thermomechanical coating.
    The purpose of the invention is to increase the optimal flow rate of the powder in the carrier gas stream.
    1 shows a distribution device, a general view; figs 2 and 3 are variants of its implementation.
    The switchgear contains at least one reservoir I with a supply of powder, the outlet aperture 2 of which is associated with an appropriate supply device. The supply device consists of a horizontally disposed pipe 3, rigidly connected with a vibrator 4 of its longitudinal vibrations and communicated from one end to the cavity of reservoir I, and from the other through the outlet 5 to the cavity of chamber 6 of the powder delivery delay. Chamber 6 has the shape of a truncated cone, facing a large base up, and is equipped with a device for monitoring the level of powder in this chamber, including sensor 7 for mass of chamber 6 with powder at the maximum level of this powder in the chamber, sensor 8 for mass of chamber 6 with powder at a minimum and a control mechanism 9 associated with its inputs with sensors 7 and 8, and the control outputs with vibrators 4, Chamber 6 through a transmission channel 10, the flow area of which is regulated by a selective organ 11, is connected with an injection device 2 in which the powder is mixed with the carrier gas stream. The device 12 is connected to the carrier gas supply line 13 and to the outlet pipe 14, into which a mixture of powder and gas enters.
    In the embodiment of the switchgear (Fig. 2), the device nodes are located so as to force the sensor 15 into force using the plate 16 common to two similar devices. The signal emitted by this sensor 15 contains information on the powder consumption, this information being indicated or recorded block 17. This information may be processed in block 18 or combined with powder level information.
    In a variant of the device (Fig. 3), an force sensor 15 is installed under each vibrator, actuated by means of a corresponding plate 6. In this case, sensors 15 send signals to recording blocks 17 and 18 and to block 19 information on powder consumption from each tank 1 separately. This information is preferably combined in block 19 with information about the level of powder in chamber 6.
    Thus, the proposed device allows you to accurately determine the flow rate of the powder supplied to the injection device from one or more tanks with a supply of powder, to ensure strict constancy of a predetermined flow rate and, if necessary, to determine the flow rate of the powder separately from each tank or in the desired proportion with the flow rate from other tanks.
